Dog allergy shots, also known as immunotherapy, typically take several months to start working. The treatment involves receiving injections of small amounts of the allergens that cause the allergic reactions. The goal of the treatment is to gradually desensitize the immune system to these allergens, so that the dog’s body becomes less reactive to them.
The length of treatment and the timing of the injections will depend on the specific allergens and the severity of the dog’s allergies. Most dogs will need to receive injections on a regular basis (usually every 2-4 weeks) for at least 3-6 months before any improvement is seen. Some dogs may continue to receive the injections for a year or more, depending on the response to treatment.
It’s important to note that immunotherapy is not a quick fix, and it may take several months or even longer for the allergy shots to start working. However, for many dogs, the treatment can be very effective in reducing allergy symptoms and improving their overall quality of life.
